目的:探讨超声造影(CEUS)在肝硬化合并肝内局灶性小病灶(≤3.0 cm)中的诊断价值。方法:选择我院自2010年4月至2014年8月患有肝硬化合并肝内局灶性小病灶的患者100例,采用MRI、CT及病理确定病灶良恶性,同时对比影像结果,计算常规超声和CEUS的准确性。结果:MRI、CT及病理确定病灶105个,其中恶性组45例,良性组60例,超声造影技术能清晰的显示出血流灌注的情况以及动脉相、门脉相及延迟相的特点。数据统计结果显示常规超声和CEUS的准确性、特异性和敏感性分别为59.05%、77.78%、45.00%和95.24%、95.56%、95.00%,两者之间的差异具有统计学意义(P<0.05)。结论:相对于常规超声,CEUS对患有肝硬化合并肝内局灶性小病灶的患者具有更高的诊断价值。
Objective: To investigate the diagnostic value of contrast-enhanced ultrasound (CEUS) in the diagnosis of focal intrahepatic focal small lesions (≤3.0 cm). Methods: A total of 100 patients with cirrhosis complicated with intrahepatic focal small lesions in our hospital from April 2010 to August 2014 were selected. MRI, CT and pathology were used to determine the benign and malignant lesions. The results of conventional imaging Ultrasound and CEUS accuracy. Results: There were 105 lesions in MRI, CT and pathology, including 45 cases in malignant group and 60 cases in benign group. Contrast - enhanced ultrasound showed clear perfusion of blood flow and characteristics of arterial phase, portal phase and delayed phase. The statistical results showed that the accuracy, specificity and sensitivity of conventional ultrasound and CEUS were 59.05%, 77.78%, 45.00% and 95.24%, 95.56% and 95.00%, respectively, with statistical significance (P < 0.05). CONCLUSIONS: CEUS has higher diagnostic value in patients with cirrhosis and intrahepatic focal small lesions than conventional ultrasound.
